The flushing and drainage device is often fixed by skin sutures, which will inevitably cause pain and injury to the patient; moreover, part of the suture is sutured on the abdominal skin, and the other part is wound and knotted to be tightened on the tube wall. A certain depression is formed by tightening when knotting to tighten the outer wall of the tube body, but the tightening force should not be too large to avoid the situation of unsmooth drainage caused by excessive deformation of the tube body, and it is easy to have insecure fixation; when the patient in the ward has sudden abdominal pain or the drainage fluid is bright red and large in volume, etc., emergency CT or ultrasound examinations are usually required, or when it is difficult for the patient in the ward to pull out the tube, there are often problems such as cumbersome operation, time-consuming and laborious, which are very likely to delay the patient's condition. Therefore, the conventional abdominal flushing and drainage device still has many deficiencies.

[0003] To sum up, it is necessary to propose a flushing and drainage device that can not only reduce the damage to the patient, but also improve the fixation and simplify the operation. Summary of the Utility Model

By providing a plurality of positioning balloons 3, it is convenient to select the balloons 3 at appropriate positions for positioning during use, with strong flexibility; positioning is performed based on the balloons 3 to form an avoidance part 31 to avoid directly pressing the skin wound at the flushing and drainage part, avoiding suture fixation and reducing the damage to the patient.

[0029] In a specific embodiment, Figure 1 、 Figure 2 and Figure 6 , it further includes a first distributor 5 and a connector 6. The balloon connecting tubes 4 penetrate into the outer drainage tube 1 from the outer wall of the front section of the outer drainage tube 1 and extend along the outer drainage tube 1.

[0033] Before use, the balloon 3 is contracted; during use, the end section of the flushing and drainage device is inserted into the patient's body. According to the insertion length of the flushing and drainage device, two adjacent balloons 3 are selected for positioning. The balloon connecting tubes 4 corresponding to the two balloons 3 are communicated with the connector 6, and gas or liquid is injected into the balloon connecting tubes 4 and the balloons 3 to make the balloons 3 expand, gradually clamping the inner surface and the outer surface of the skin to fix the flushing and drainage device, without the need for suture fixation, avoiding causing damage to the patient; when the two balloons 3 clamp the inner surface and the outer surface of the skin, stop injecting gas or liquid. Since the longitudinal height of the expanded balloon 3 gradually increases along the direction away from the external drainage tube 1, an avoidance part 31 for avoiding compressing the skin wound at the flushing and drainage place is formed between the two adjacent expanded balloons 3; after positioning, the flushing liquid supply device injects flushing liquid into the internal flushing tube 2 for flushing; the air pressure is balanced through the ventilation tube 8 and the ventilation channel 21; the external drainage tube 1 is connected to a negative pressure device for negative pressure drainage, and the effusion flows into the external drainage tube 1 through the through hole 11 of the external drainage tube 1 for drainage.
